ORGANIC LUMINESCENT DISPLAY DEVICE

Organic luminescent elements forming an R sub-pixel, a G sub-pixel, and a B sub-pixel are formed of lower electrodes (3, 4, and 5), hole-transporting layers (7, 8, and 11), luminescent layers (9, 12, and 14), electron-transporting layers (10, 13, and 15), and an upper electrode (16), and each of the...

Zusammenfassung:Organic luminescent elements forming an R sub-pixel, a G sub-pixel, and a B sub-pixel are formed of lower electrodes (3, 4, and 5), hole-transporting layers (7, 8, and 11), luminescent layers (9, 12, and 14), electron-transporting layers (10, 13, and 15), and an upper electrode (16), and each of the organic luminescent elements optimizes an optical interference condition. A dielectric alternate laminated film (17) is formed on the upper electrode (16), and forms a micro-resonator with each of the lower electrodes. The micro-resonator structure raises the directivity of a radiation pattern, and improves the light extraction efficiency of each of the organic luminescent elements. A narrow radiation pattern is alleviated by a view angle-controlling layer (19) formed on the dielectric alternate laminated film (17) so as to broaden until a perfectly diffusing surface radiation pattern. Consequently, the light extraction efficiency can be improved in an organic luminescent display device.
